Material Matters: Selecting the Right Absorbing Materials for EMC and Compliance Testing

Choose the wrong absorber and even a well-built test setup can produce misleading results. Compare ferrites, polyurethane foam, conductive polymers, and magnetic sheets by frequency range, absorption, and durability to match the right material to your application.

Why the Hazards of Lithium-Ion Batteries Require a Different Approach to Safety

As lithium-ion battery energy storage systems scale up, so does the risk when something goes wrong. Drawing on FDNY's frontline experience, this article breaks down thermal runaway, propagation, and the codes, testing, and installation practices that determine whether a battery failure stays contained or turns catastrophic.

The Impact of Power Flow Analysis on an Electrical System

Constant-power loads break the assumptions behind linear circuit analysis, and the fallout shows up as undersized batteries, excess heat, and stressed inverters. New drivetrain testing on a Kia EV-6 reveals why batteries, inverters, and motors need to be modeled together, not separately, to get electrified powertrains right.

2.5D/3D Integration Challenges: Bare Die Testing

As chiplets shrink toward 10 micron pitches, standard CDM testers can no longer verify their ESD withstand voltage before 2.5D/3D assembly. This first installment breaks down why existing test methods fall short and maps out the emerging paths, from contact-based CDM to correct-by-design verification, for closing the gap.

Walking the Line: The Interaction of Flooring and Footwear in Walking Body Voltage Generation

New research reveals that certified ESD footwear and compliant flooring do not guarantee protection on their own. Testing across multiple systems shows some combinations pushed body voltage past 350 volts, well beyond the ANSI/ESD S20.20 limit. See which pairings held up.

Basing CDM ESD Test Goals on Fundamental Limits

Setting CDM test goals has long lacked clear guidance on what counts as adequate performance. New analysis grounded in radial transmission line theory calculates fundamental limits on peak current and slew rate for devices of any size, offering engineers a way to evaluate risk against real use conditions.
